This document discusses three common methods of qualitative research: participant observation, in-depth interviews, and focus groups. Participant observation involves researchers observing participants in their natural environment. In-depth interviews are unstructured conversations where interviewers encourage interviewees to openly discuss their lives. Focus groups involve moderated group discussions on a particular topic where a moderator sets rules and takes detailed notes. The document provides details on how to properly conduct each method and considerations like obtaining consent and writing field notes.
